Beschreibung
Zusammenfassung:	A magnetic resonance imaging (MRI) method and apparatus in which conductors are installed in the space between a static coil unit and a gradient coil unit to eliminate asymmetry of eddy current induced in the static coil unit. The structure permits a symmetrical distribution of eddy current when the concentric arrangement of the static coil unit and gradient coil unit has deviated. The MRI apparatus includes: a static coil unit configured to form a static field in a subject; a gradient coil unit configured to form a gradient field in the static field; and one or more conductors installed in the space between the static coil unit and the gradient coil unit, and configured to symmetrically distribute eddy current induced in the static coil unit.
